Subject: [PATCH v2 1/2] dt-bindings: drm/bridge: MHDP8546 bridge binding changes for HDCP
Date: Mon, 1 Mar 2021 12:22:26 +0100 [thread overview]
Message-ID: <1614597746-4563-1-git-send-email-pthombar@cadence.com> (raw)
In-Reply-To: <1614597685-4192-1-git-send-email-pthombar@cadence.com>
Add binding changes for HDCP in the MHDP8546 DPI/DP bridge binding.
This binding is not used in any upstreamed DTS yet, so changing
index of property 'j721e-intg' should not affect anything.
